| 13664278502 | camouflage | A structural adaptation that enables an organism to blend in with its environment |  | 1 |
| 13664278503 | survival of the fittest | Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called natural selection |  | 2 |
| 13664278504 | competition | Interaction among organisms that vie for the same resource in an ecosystem |  | 3 |
| 13664278505 | variation | Differences in traits among individual organisms within a population |  | 4 |
| 13664278506 | natural selection | Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest | 5 | |
| 13664278507 | adaptation | A trait that helps an organism survive and reproduce in its environment |  | 6 |
| 13664278508 | mimicry | Gaining protection by looking and acting like a different species |  | 7 |
| 13664278509 | vestigial organ | an organ that is not functional in an organism, but was functional at some period in its evolution | 8 | |
| 13664278510 | favorable traits | Offspring with favorable traits survive and reproduce, passing on their traits to another generation | 9 | |
| 13664278511 | evolution | Change over time |  | 10 |
| 13664278512 | Lamarck | French naturalist who proposed that evolution resulted from the inheritance of acquired characteristics (1744-1829) |  | 11 |
| 13664278513 | Darwin | A biologist who developed theory of evolution of species (1859). He argued that all living species evolved into their present form through the ability to adapt in a struggle for survival. | 12 | |
| 13664278514 | Galapagos Islands | Chain of islands near South America where Darwin developed his theory of natural selection by studying the unique life there. |  | 13 |
| 13664278515 | finches | Observed by Darwin. Very similar, but differences can be seen in the size and shape of the bill and/or beak. |  | 14 |
| 13664278516 | mutation | (genetics) any event that changes genetic structure | 15 | |
| 13664278517 | use and disuse | Theory proposed by Lamarck that said body parts develop with increased usage while unused parts weaken. "Use it or lose it!" |  | 16 |
| 13664278518 | Trait | A characteristic that an organism can pass on to its offspring through its genes. |  | 17 |
| 13664278519 | Heredity | Passing of traits from parents to offspring |  | 18 |
| 13664278520 | artificial selection | Breeding organisms with specific traits in order to produce offspring with identical traits; SELECTIVE BREEDING |  | 19 |
| 13664278521 | Fossils | Preserved remains of once-living organisms; evidence for Evolution | 20 | |
| 13664278522 | homologous structures | Structures in different species that are similar because of common ancestry but different because of adaptation to different environments. |  | 21 |
| 13664278523 | Analagous Structures | similar structure without having a common ancestor |  | 22 |
| 13664278524 | evolutionary tree | A branching diagram that reflects a hypothesis about evolutionary relationships among groups of organisms. |  | 23 |
